Remember to look at dream symbols in a spiritual light. A purse or wallet most likely doesn't mean a literally purse or wallet. In dreams, wallets and purses can represent your life or your identity. Think about it: your wallet or purse contains all of your personal information. It contains confidential and private information such as bank cards or financial documents, as well as your identification and picture IDs. It usually contains your money, your personal treasures.
When you lose your purse or your wallet you have to cancel the cards and go through a lot of trouble to get new ID. Thieves can use this information to pretend to be you. Sometimes wallets and purses contain things that are irreplaceable, valuable and precious to you, the owner. If you dream of your purse or wallet being stolen, God could be communicating that the dreamer has lost (or is looking for) his or her purpose, identity, or favour.
Dreaming of your purse or wallet being totally empty can be God's way of revealing to the dreamer that they are spiritually "bankrupt".
Matthew 6: 21 says, "For where your treasure is, there your heart will be also."
Your literal "treasure" is often found in your purse or your wallet (or at least your way to "access" your literal earthly treasures). So your spiritual treasures can be found in your spiritual purse/wallet... your heart, which contains your personal identity, your spiritual treasures and gifts, and those things that are valuable to you in a spiritual sense.
To check your financial status, you use your banking information contained in your wallet/purse, but God can give you a dream about your purse or wallet as a way of giving you a "status update" or report on your spiritual treasures and spiritual identity.
Matthew 12: 35, "The good man brings good things out of the good stored up in him, and the evil man brings evil things out of the evil stored up in him."
Judas, the disciple who betrayed Jesus showed his spiritual identity in a parable of the bible, and here a purse is mentioned, so we get a biblical context to support the biblical interpretation of the symbol:
John 12:4-6, "But Judas Iscariot, one of his disciples (he who was about to betray him), said, 'Why was this ointment not sold for three hundred denarii and given to the poor?' He said this, not because he cared about the poor, but because he was a thief, and having charge of the moneybag he used to help himself to what was put into it."
Pretty cool, actually! Happy interpreting!
